-scopolomine for motion sickness can interact w/:
fu ling, dang gui, ren shen, shi chang pu, yuan zhi
CNS?
-made up of the brain & spinal cord
-cns presynaptic neurons release neurotra into the synaptic cleft, activating the postsynaptic membrane receptor, *causing voltage changes in the postsynaptic neuron
cns vs ans?
-cns uses *more neurotrans than ans
-neurons in cns have more connections with other neurons
-neurotra inhibit as well as excite postsynaptic neurons, making action more potentials more/less possible
membrane potential & threshold?
-an example of an interaction in which Ach is the neurotra. Achs role in the cns is very different than in the ans.
-Ach is only 1 of the many neurotra active in cns & that Ach is an excitatory neurotra in this case, making an action potential more likely
depolarization?
1. ion flow through ion channels can cause hyperpolarization or depolarization, depending on which ions flow in or out and how much change in charge occurs
-think of depolarization & hyperpolarizing as directions on a continuum
-hyper=inhibitory
-depol-excitatory
2. sufficient depolariztion initiates an action potential
3. depolarization is called an excitatory post-synaptic potential-epsp
-+ likelihood of a nerve impulse
-caused by an influx of Na ions.This makes the - int. of the cell less - (more +) by the addition of + charged ions
-nore & epi are common epsp neurotra in cns
hyperpolarization?
1. inhibitory post synpatic potential (ipsp) come from hyperpolarization of the postsynaptic membrane reducing the likelihood of generating an action potential
-caused by an influx of CL ions or outflow of Na ions
-makes the int of the cell membrane more - makes it more difficult to depolarize & thus more difficult to cause an action potential
-gaba & glycine common ipsp neurotra
cns neurons?
-most recive both epsp & ipsp
*the sum of these determines if an action potential will be initiated
drugs of cns?
-parkinsons
-anxiolytic & hypnotic
-cns stimulants
-antidepressants
